Abstract
A fast-release retardance valve for an automobile clutch comprises a valve body, an oil inlet and an oil outlet, and is characterized in that a buffer sliding body is arranged at the oil inlet end of the valve body, a cylindrical cavity with an opening is formed in one end of the buffer sliding body, a throttling hole is formed in the end face of the cylindrical cavity, a pressure storage plunger is arranged in the valve body, a reset spring is arranged between the pressure storage plunger and the buffer sliding body, the other end of the pressure storage plunger is in contact with an inner buffer spring and an outer buffer spring, and the oil outlet of the valve body is formed in the side face of the oil inlet end of the valve body. The fast-release retardance valve for the automobile clutch is simple in structure and is connected with an automobile clutch slave pump through a clutch hose, oil inlet pressure can be controlled, output torque disturbance can be reduced, and the gear shifting process is stable and smooth.
Description
Technical field
The utility model relates to automobile component, and especially a kind of automobile clutch slows down fast valve soon.
Background technique
Gear shift sleeve is as the important component part of vehicle planetary transmission, in gearshift procedure, by controlling in conjunction with pressure from zero variation to rated pressure, not only can produce wear smooth steadily accelerates vehicle, reduce shifting shock, but also link is insured in the friction that can be used as power train, to prevent overload.Gearshift procedure carries out hurriedly, can produce larger impact and dynamic load, affects gear shift smoothness.After gearshift, while releasing the pedal, unskilled due to too urgent and action in operation, lifts leg too fast while releasing the pedal, closed too quickly, while making low engine speed, instantaneous output does not catch up with wheel shaft required torque, cause motor serious overloading in short-term, occur vehicle body shake and with noise, even engine misses, this not only can affect the rideability of vehicle, and is a unsafe factor.
Summary of the invention
The purpose of this utility model is just to provide a kind of simple in structure, can control input pressure, reduces output torque disturbance, makes the automobile clutch of gearshift procedure steady and smooth slow down soon fast valve.
Automobile clutch of the present utility model slows down fast valve soon, comprise valve body, filler opening, oil outlet, it is characterized in that, the filler opening end of valve body arranges buffering gliding mass, the cylindrical cavity that buffering gliding mass one end is opening, and the end face of cylindrical cavity has throttle orifice, pressure accumulation plunger is arranged in valve body, between pressure accumulation plunger and buffering gliding mass, be provided with return spring, the other end of pressure accumulation plunger contacts with outer damping spring with interior damping spring, and valve body oil outlet is established on the side of valve body filler opening end.
Automobile clutch of the present utility model slows down fast valve soon, be connected with automatic clutch wheel cylinder by clutch flexible pipe, when work, in the time that pedal moves and starts to clutch oil-feed, fluid is exported the low order end that slows down soon fast valve simultaneously, its oil pressure thrust left and the tension force of inside and outside damping spring balance each other, and slow down soon fast valve and remain on initial position.In the time that oil-feed process is carried out, buffering gliding mass and pressure accumulation plunger, all to moving to left, so that buffering gliding mass is opened the oil outlet that overflow is used, are limited in lower scope the oil pressure that cushions guiding valve right-hand member oil duct.The inside and outside damping spring tension force in this oil pressure and pressure accumulation plunger left side balances each other.Meanwhile, the fluid on buffering guiding valve right side flows to the inner chamber in gliding mass left side through the trifle discharge orifice at gliding mass top.The fluid that flows into gliding mass inner chamber is set up certain oil pressure gradually, and this oil pressure will balance each other with the load of damping spring inside and outside pressure accumulation plunger left end on the one hand, will balance each other with the controlled oil pressure of buffering gliding mass 1 right-hand member on the other hand.Because return spring 2 acts on the left end of buffering gliding mass, can keep certain pressure difference in the front and back of throttle orifice, and this pressure difference while moving to left with accumulator plunger return spring extend and reduce gradually.Utilize ever-reduced pressure difference, can control by the flow of throttle orifice and also reduce thereupon.Like this, pressure accumulation plunger is moved to the left with ever-reduced speed.Inside and outside damping spring increases compressive strain thereupon lentamente, and result is that the oil pressure in clutch oil cylinder is also gradually increased.Now, buffering gliding mass only has small moving right, to regulate the flow of overflow.Until pressure accumulation plunger moves to left when spacing to being withstood, oil pressure just rises suddenly to main pressure value.
Automobile clutch of the present utility model slows down fast valve soon, simple in structure, and it can control input pressure, reduces output torque disturbance, makes gearshift procedure steady and smooth.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
